Title: Electric switch with conductive plastics contact
Inventor: KNIGHT JONATHAN
IPC: H01H1/029
Filed: 1981-10-06
Abstract: An electric switch has one of its contacts (2) formed by a conductive plastics layer on the inside of a resiliently flexible sleeve (1). When gripped, this constricts onto a core (3) whose outer surface has terminals (7, 8), conveniently in the form of conductive zones separated by an otherwise non-conductive surface. These zones may be interdigitated fingers, so that however the sleeve is grasped at least some will be bridged by the inner layer of the sleeve to close the switch. An application of this type of switch is to game apparatus (fig. 3 not shown) in which each one of a number of handles (10, fig. 3) has such a switch incorporated, and whichever handle is grasped the associated switch closes. This signals to a microprocessor in a central body (11 fig. 3) and the closures are correlated to a game programme. <IMAGE>

Patent GB-2114913-A (GB)
Title: Exhaust gas treatment apparatus and method
Inventor: VIRK KASHMIR SINGH
IPC: F01N3/36
Filed: 1982-02-10
Abstract: Apparatus and method for filtering combustible particles from an exhaust gas stream, and for periodically rejuvenating the filter bed (19) and catalyst portion (32) thereof, by incinerating retained particles. A portion of an exhaust gas stream is heated (36) upstream of the filter so as to raise the catalyst to a temperature above the temperature at which the catalyst can initiate combustion of said particles. A small amount of a supplementary fuel is injected (52) into the exhaust gas stream prior to the latter entering the catalyst section, thereby causing the heated fuel/gas mixture to ignite. Subsequent to initiation of the oxidation reaction, further preheating energy input can be discontinued without affecting the combustible particle incineration rate. The supplementary fuel is preferably brought into heat exchange contact with the filter to heat the fuel prior to its injection into the exhaust gas stream. A controlled rate of carbon removal from the exhaust gas stream can thus be achieved without damage to the filter by thermal shock. <IMAGE>
